![]() You can set up scary digital Halloween decorations in the time it takes to cover a window and turn on a projector. And I tried out something so scary and creepy and cool, I can’t believe how easy it was! And the best part? It’s all done from inside! No standing in the cold hanging things up, no worrying that the decorations will get stolen. So my only real option is to decorate my windows. One Halloween I hung five or six adorable glowing scary-face balloons from a tree, and by the end of the evening, they were all gone! ![]() For another, even if I wanted to put elaborate decorations out there, they wouldn’t last ten minutes if someone weren’t watching them closely. For one thing, my front yard is the size of a postage stamp. This force is much too powerful and the ring degloves the entire finger.When I drive around in the suburbs I get really jealous of the huge outdoor Halloween displays. He is moving so fast, that when his ring gets caught, the force acting on the ring is equal to his body weight multiplied by the acceleration. ![]() The most common mode of such an occurrence is when a person is getting down from a bus, and his ring gets caught in some metallic projection on his way down. When a person is wearing a ring and the hand is moving very fast in a particular direction, and the ring gets caught by a sudden stopping force, a ring avulsion injury occurs. There is another common cause of degloving injury involving a single finger. However, the conveyor belt machine has a rough surface, which can hold on to the skin of the hand and cause a degloving injury. Hence the usual injury in such an accident is a brachial plexus injury. The roller machine usually does not get a hold on the skin, and hence, the force that pulls the hand out is not restricted to the skin, but pulls the entire upper limb outwards, and the entire load falls on the axillary region - the root of the limb. ![]() In industrial accidents, there are two types of machines that can cause an outward force on the hand that has been caught in it - the conveyor belt and the roller machine. A higher speed usually results in injury to the underlying soft tissues and skeletal framework leading to fractures and muscle / tendon injuries. As mentioned earlier, when this mechanism is the cause of a degloving injury, it is usually a low force - a two wheeler tyre moving fast over the hand or a low velocity - a four wheeler tyre moving at a low speed. In road traffic accidents, the usual mode of injury is the tyre of the vehicle running over the outstretched hand and forearm. The most common causes are road traffic accidents, conveyor belt injuries and ring avulsion injuries. ![]() When this then pulls in an outward direction - it may be the force moving outward, like the tyre of a vehicle that has run over the hand or it may be the counter force - the patient pulling his hand outward - for example, from a machine in which his hand has been caught. The force that holds the skin usually has some amount of irregular surface, that holds on to the skin and does not slip. These injuries occur when the hand is caught by a force and pulled at a low velocity. ![]()
